*Explanation of polite formThe words with green color in the bracket are polite form. For example, if only the word in bracket is green such as 'ureshii(desu) ', you can just put 'desu' after 'ureshii' so this word's polite form is 'ureshii desu'.

But if the word in the bracket and also the word before the bracket is green such as 'suteki da(desu)', you need to change 'da' into 'desu' so this word's polite form is 'suteki desu'.
